Application filed February 1, 1919., Serial No. 274. 458.

To all 20/2/0122 it may concern Be it known that 1, PAUL J. ONEILL, a citizen of the United States, residing at De troit, in the county of ll ayne and State of Michigan, have invented new and useful Improvements in hiotorcycles, of which the folloi'ving is a specification.

This invention relates to a novel construction of means for warming the hands and feet of a, motorcyclist by the exhaust gases.

The object of the invention relates to the construction of the radiators for the foot rest and handle bars of the motor cycle and to the means for carryii us exhaust from the muffler to l said radiators.

The invention also consists in certain other features construction and in the of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the sev eral views, and in which it igure 1 is a side View of part of a motorcycle showing my invention in place thereon.

Figs. 52 and 8 are detailed views of the radiator.

In these views, the frame of the motorcycle is indicated at 1, the handle bars at 2, the foot rest at 8 and the muffler at e. 5 indicates the radiators which are placed on the handle hers and on the foot rest. As shown, these radiators of substantially funnel shape so as to inclose the grip of the handle hars and the foot rest in such a mannor that the feet and hands of the operator can he introduced into the radiators with out interfering with the proper operation of the parts. Each radiator has its walls of double formationso as'to leave space 6 Specification of Letters Patent.

into which the gases circulate. If desired, 1 inay place baffle plates in said spaces. The radiators connected with the outlet of tie rouiiier by the means of the piping 7, which is suitably secured to the frame bars of th machine. Valves 8 are placed in said lg to control the passage of the gases -e radiators. The radiators are supplied with the outlets 9. The radiators are secured in position by suitable clips or the y may he removed and replaced, when desired.

I place an outlet 3 in the muffler conve re having" a weak spring so she valves controlling the flow of exhaust gases the radiators are closed the exhaust will orercome said spring so as to pass through the outlet.

It will be seen that the gases flowing through the radiators will heat the hands and feet of the operator and at the same said liators will act as shields to profrom the cold air.

.. 3 bile hands and feet it is thought from the foregoing description that the ad; ages and novel features of my invention will he readily apparent.

v be understod that I may l desire to make changes in the construction and in the combination and arrangement of the sev eral parts, provided that such changes fall within the scope of ieappended claim.

lV hat I claim is The combination with a motorcycle of funnel-shaped casings attached to the frame thereof and surrounding the hand grips and the foot rests, said casings having double walls, inlet and outlet pipes communicating with the space between the double walls of the casings, valves in the inlet pipes, a pipe connecting the inlet pipes with the outlet of the muffler, said pipe having an opening therein and a spring controlled valve controlling said opening. 7

In testimony whereof I fi-lllX my signature.
